The Home Office is testing a new form of chemical gun, which could be used to control rioters and can be fired from more than 100 feet away.

Tests of the Discriminating Irritant Projectile (DIP) – a form of gun that will fire an irritant substance like CS gas or pepper spray – are believed to be in the late stages.

The gun has a far greater range than a Taser, which can be fired from 21 feet.

It was put forward for testing along with ideas to use skunk oil pellets and anti-laser technology by Government scientists as a method for controlling future protesters in the wake of the 2011 riots, which took place across the country.
